Abstract 4123864: Fractional flow reserve-guided complete revascularization versus culprit-only revascularization in patients with myocardial infarction and multivessel disease: A GRADE assessed meta-analysis of randomized controlled trials

Circulation, Volume 150, Issue Suppl_1, Page A4123864-A4123864, November 12, 2024. Background:Fractional flow reserve (FFR) guided complete revascularization (CR) is an approach that can be used to improve clinical outcomes in patients with acute myocardial infarction (MI) and multivessel disease (MVD). The objective of the present meta-analysis was to investigate whether FFR-guided CR leads to better cardiovascular outcomes as compared to culprit-only revascularization (COR) in acute MI and MVD by pooling recently published data.Methods:A comprehensive literature search was conducted using PubMed/MEDLINE, Embase, and the Cochrane Library from inception until April 2024 to retrieve eligible randomized controlled trials (RCTs). Clinical outcomes were assessed using the random-effects model by pooling risk ratios (RRs) along with 95% confidence intervals (CIs). We assessed the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology.Results:Four RCTs were pooled with 3,175 patients. FFR-guided CR significantly reduced the risk of repeat revascularization as compared to COR (RR = 0.52; 95% CI: 0.33-0.81, p = 0.004) [absolute risk difference 83 fewer per 1,000 patients (95% confidence interval: 116 to 33 fewer) moderate certainty]. Though there was a reduction in the risk of MACE with FFR-guided CR (RR = 0.68, 95% CI: 0.44-1.04,p= 0.08; moderate certainty), it didn’t attain statistical significance. Clinical outcomes such as all-cause death (RR = 1.10, 95% CI: 0.84-1.45, p = 0.48; moderate certainty), cardiac death (RR = 0.79, 95% CI: 0.53-1.17, p = 0.24; high certainty), risk of MI (RR = 0.94, 95% CI: 0.54-1.66, p = 0.84; moderate certainty) and major bleeding (RR = 0.95, 95% CI: 0.54-1.67, p = 0.87; moderate certainty) were comparable between the two groups.Conclusion:FFR-guided CR in patients with MI and MVD can lead to a decreased risk of repeat revascularizations while not affecting all-cause and cardiac deaths.

Abstract 4132742: Fractional flow reserve guided complete revascularization versus Culprit-only percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction and multivessel coronary artery disease. A meta-analysis of randomized controlled trials

Circulation, Volume 150, Issue Suppl_1, Page A4132742-A4132742, November 12, 2024. Background:Data comparing the efficacy and safety of fractional flow reserve (FFR)-guided complete revascularization (CR) to culprit-only percutaneous coronary artery intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease are limited.Method:Pubmed, Embase and Cochrane were searched for randomized controlled trails (RCTs) comparing FFR-guided CR to Culprit-only PCI in patients with STEMI and multivessel CAD. A meta-analysis was performed on primary outcomes of major adverse cardiac events (MACE) and all-cause mortality. Heterogeneity was examined with I2statistics. A random-effects model was used for outcomes with high heterogeneity.Results:We included 4 RCTs with 3173 patients comparing FFR-guided CR with culprit-only PCI in patients with STEMI and multivessel coronary artery diseases. The pooled results of the 4 RCTs showed that MACE (RR=0.66; 95% CI [0.45, 0.99]; p=0.01; 16.8% vs 24.1%), PCI revascularization (RR=0.50; 95% CI [0.37, 0.67]; p

Abstract 4146729: Residual Angina Following Anatomic Complete Revascularization for Chronic Coronary Disease in the ISCHEMIA Trial: Frequency, Characteristics, and Outcomes

Circulation, Volume 150, Issue Suppl_1, Page A4146729-A4146729, November 12, 2024. Background:Although residual angina after revascularization for chronic coronary disease (CCD) is common, it is unclear if the cause is incomplete revascularization of epicardial coronary disease or other ischemic mechanisms such as microvascular dysfunction or vasospastic angina.Methods:Among invasively managed ISCHEMIA trial participants with angina at baseline and anatomic complete revascularization (ACR) determined by core lab analysis, the frequency of and characteristics associated with residual angina and its association with health status, medication use at 6 months, and 5-year all-cause and cardiovascular (CV) mortality were assessed. The Seattle Angina Questionnaire Angina Frequency (SAQ AF) was used in a binary fashion to define residual angina as a score
